CORE OR WINDER FOR FABRIC STRIPS AND METHOD OF MAKING SAME.

Application led February 21, 1922. Serial No. 538,289.

To aZZ whom. t may concer-n Be it known that I, HARRY BRIDGMAN SMITH, a citizen of the United States, and resident of Brooklyn,` in the county of Kings and State of New York, have invented cerpieces upon which strips of fabric such as.

braid, lace, fringe or other material may be Wound for exhibition and sale, such devices being convenientl called winders,` and to rapid and economlcal methods of producing such articles.

An important object of the invention is to provide an improved structure for winders of this sort which permits them to be made of cheap and easily worked material, such as cardboard and paper, and at the same time to have a desirable and attractive appearance and finish Another important object is to provide methods of manufacture which'are suitable for materials such as those just mentioned, and which can be performed rapidly and economically by machine operations, or partly by machine operations and partly by hand in some cases. As to the method, while it can in some cases be-performed entirely by hand operations, it is especially desirable that the winders may be produced largely or wholly by mechanical operations; and an important advantage of'one preferred method as disclosed herein is that 1t provldes for the advancing and associatlon of continuous strips ot' material to forln a composite continuousassembly or blank from which individual cores or winders are formedby severing the fxomposite assembly strip at regular intervals. Y

lVhile cardboard is usually the most available and desirable material for the bases or bodies of the winders, and paper of diil'ersheet material, abrio or fibrous material' may be used Where conditions make it desii-able, andvwhere they are suitable foi' the particular purpose in View.

vThe characteristics and advantages ofthe invention are further sufficiently explained in connection with the detail description of the. accompanying drawings, which show certain exemplifyingembodiments ofthe inventi on, that is to say, certain representative forms of the cores or Winders, and diagrams illustrative of certain performances of the method. After considering theseexemplifications, persons' skilled in the a'rt will understand-that many variations may be made within the principles of the invention, and I contemplate theemployment of any structures and methods which are properly Within thescope of the appended claims.

In the drawings:

Figure 7 is a perspective view illustrative of a modified method; and

Figure 8 is a. plan view of an individual Winder produced by the method of Fi reY 7 According to the method exempli ed in Figure 1, a continuous strip 1 of cardboardl is advanced from a roll 2 carried by a rotatable shaft 3. The cardboard 1 is of suitable quality and has substantial thickness and stiffness, the thickness and stiffness ofthe cardboard body` materialv usually being va- Vfm ried in accordance with the size of the Winder to be produced, the number of layers ofbody material to be used, and other conditions. The cardboard stri 1in the present case represents any suitab e body material, and in the broader aspect of the. invention this material is not necessarily limited to cardboard, although usually some fibrous material will be used. Another strip 4 of cardboard is advanced from a roll 5, this material usually bein of the same grade and thickness as strip l. (yrior to engagement of the two strips, they are adhesively conditioned, or adhesive is applied to at least one of them, means for this purpose being suficiently indicated in the form of a glue roll 6 supplied by dipper roll 7 running in a glue trough 8, the glue roll 6 engaging the.under surface of strip 1. After the glue application the strips are brought together between pressing rolls 9 and l() and are firmly pressed together.

A continuous strip 11 of cover material, in the present instance paper, of suitable grade and finish, is advanced 'from a roll 12.

This paper represents in the broader sense any suitable covering or surfacing material, and in some cases-other material than paper can be used, such as a woven fabric, or other material capable of being manipulated in the ways described. Before being incorporated in the blank assembly, strip 11 is adhesively conditioned, in the 4present instanceby carrying it over a glue roll 13.

Strip 11, as best shown in Figures 2 and 3, is desirably of about the same Width as the body strips 1 and 4, or in the present specic instance is slightly narrower-than those strips. Another continuous strip 1.4 of paper covering or finishing material is advanced from a roll 15 over a glue roll 16 and about an idler roll 17, and this strip is desirably, as also best shown in Figures 2 and 8, considerably wider than the cardboard strips 1 and 4. The twosurfacing or cover Strips 11 and 14 are now brought with their adhesive faces in contact with upper and lower surfaces of the composite cardboard body strip and pressed between rollers 18 and 19, so that the proper adhesive contact of all of the strips up to this point is insured.

The projecting adhesively coated margins 2() of strip 14 are now turned over the longitudinal edges of the body strips and'then brought over upper surface margins of body strip 11, this turning and locating of the margins 20 being accomplished in the present instance by stationary folders 21. The margins are then pressed down and secured by rollers 22 and 23.

The blank assembly from this point onward is complete, and consists in the present instance of two sheets of cardboard body material in adhesive contact with an upper and lower sheet of covering material adhesively` aiiixed and with margins of one of the sheets cf covering material turned over and adhesively secured, so that the edges as well as all other surfaces of the cardboard body material are covered and concealed by the surfacing material.

yA t a suitable point in the advance of the continuous assembly it is cut transversely at regularly spaced intervals, these cutting actions severing successive sections W, each of which is a finished Winder or core piece.

In order that the winders may have the propeil end conformation, the severing operation is desirably performed in such. a way that central portions of the ends of the Winder are indented as at 25, these indented portions extending usually close up to the margins defined by theV overturned cover margins 20, and leaving projecting marginal portions 26 which serve to confine material such as braid or other strip fabric to be wound upon the Winder in the usual way.

The desired end conformation is produced, in the particular example represented in Figure 1, by a cutting device 30, which is in this particular instance a rotary cutting device provided With cutting dies or blades 31, Abut may otherwise be a reciprocating cutter. The rotary cutter 3() cooperates with an abutment roll 32. The cutting dies or blades 31 are formed so that pieces 35 are cut out from central portions of the blank, producing the incurved or indented end formations 25, and at the same time the marginal vportions of the blank are cut straight across on lines 36, Without excision of material.

It is evident from the foregoing description that the assembly and severing operations may be carried on continuously and rapidly, and a very large number of winders may be economically produced.

The winders W produced in the manner describedfeach consists of two pieces of cardboard body material cemented together, a sheet of finishing or surfacing material overlying one side of thecomposite body, and another sheet of surfacing material overlying the other side of the body and having margins turned over and secured to margins of the body on the opposite surface,l these overturned margins in the present example of course overlying marginal portions of the narrower surfacing sheet: and central portions of the ends of the body are inout or recessed. leaving marginal projections, this end conformation definitely defining a winding space for the fabric.

In some eases a single strip of body material. such as 1, may be used. and the process of production will then be the same as'represented in FigureV 1, with the omission of the second strip of body material 4. i In such a case 'the method provides for completely covering a strip of raw or uncovered cardboard and putting it in presentable condi- ISO ' cutting off and properly forming the individual winders.

Another variation of the method and product is sufficiently shown in Figures 4 and 5. In thiscase the two strips of body material 1 and 4 are adhesively secured together as before, and each is provided on lts outer surface with an adhesively secured strip ofv cover material and 41 respectively, and these cover strips may be applied after the fashion shown in Figure 1, withv the exception that the lower cover strip 41 is in this instance only of substantially the same width as the body stripg-or these cover strips may have been originally applied to the cardboard previous to the utilization of the cardboard in the present process, that is tosay, cardboard body strips 1 and 4 may be secured, each provided with surfacing or finishing paper applied to one side, and may .in this condition be fed from the rolls 2 or 5 and cemented together with the `finished surfacesoutward. Edge finishing strips 45 and 46 are then advanced and adhesively conditioned, for instance by applying glue -to one surface of each strip as indicated in tion as shown at the right in Figure 4 and also in the sectional view, Figure 5.

In this case the cover strips so vfed and f applied serve principally to` provide 'an edge or marginal finish for the assembly, and particularly to cover the side 'edges of Y the cardboard body'strips. This method of edge finishing may be employed in connection with a single body strip, which may or may not have strips of surfacing material applied toits surfacesyand in the case where the body strip is unfinished except for the edge finishing strips, the latter serve to properly conceal. and decorate the marginal portions of the cardboard body which are exposed wheny the Winder is filled by winding strip fabric 4upon it, the raw or unfinished portion of the cardboard body being concealed by' the applied fabric material. Otherwise, where edge finishing strips are use-d with surfaced cardboard body strips, the edging strips may be of a different material or material contrasting in color with the other surfacing material .for the purpose of producing novel or attractive decorative effects.

Figure 6 is a crossfsectional and perspective view of oneform of continuous 'assembly in which cardboard body strips 1 and 4 are unfinished and are provided'wit-h edging strips' 45 and 46 overlying the raw edges of the body material and adhesively secured to upper and lower marginal surfaces of the body. In some'cases when the cardboard body material. is quite thin, or for other reasons, the finished winders have more or less tendencyfto warp, which is undesirable for the purpose in view; and to obviate this difficulty an assembly method and structure sufficiently illustrated in Figures 7 and 8 may be employed. According to this form of the invention a body strip 1 is advanced as usual and adhesively conditioned by glue roll G, as in the first instance.A The fibres composing the cardboard strip 1 run mainly in the longitudinal direction of the strip. At a suitable point in the advance of this .body strip, pieces 50 of cardboard body material, which may be the same kind of stock as thev strip 1, are advanced and applied to the glued surface of strip 1 with their edges 51 and 52 located close together, so that the entire surface of strip 1 is covered by pieces 50, the-side edges 53 of pieces 50 being of course so spaced that the width of the pieces 50 is the same as that of the strip 1. The pieces 50 may be handled as separate sheets, or they may. befed from a roll, as in the case of strip 1, and cut off at or adjacent to the point of application. pieces are handled, they are arranged so that their fibres run mainly in the direction transverse the fibre arrangement of strip 1,

4as sufficiently indicated by surface shading on the respective strip and pieces 50.

The pieces 50 are properly pressed 1n adhesive engagement with strip 1, and at a suitable point when necessary or desirable, another strip 55 of body cardboard 'material is' advanced from a roll 56 and adhesively conditioned, as sufficiently indicated by .ntipplingon the upper surface of this strip, and applied to the lower surfaces of the pieces 50, and the whole strip assembled is then pressed and secured by rollers 57 and 58. Surface stripsl lland 14 are then advanced and applied to the assembly, and the assembly is finished and individual winders'Y are cut off, as in the first described example.

The completed winders made in this fashion as shown inFigure 8 consist of lay However the leu described transverse libre arrangement any curling tendency of one part of the body material is counteracted by the other, and \varping is practically prevented.

It is desirable in many cases that the completed Winders shall bear imprints to designate the nature or quality of goods Wound .upon them. At a suitable point in the continuous process, for instance between the rolls 22 and 32, Figure l, suitable printing mechanism may be provided consisting in the present instance ot' a printing roll (SO ar angel to carry suitable type in lineu'ith one of the margins 20, and suitable means are prov'ded for inking the type, suiiiciently exemplified by an inltivell Gl. Of course' the printing mechanism may be arranged to make an imprint upon both margins 20 if necessary or desirable. F igure 8 shows imprints madeupon the` margins atl the points 65 and G6, consisting of the Words Lot and Style 7 or any other suitable indicia.
